| Abstract: | Detailed measurements of CH4 in the water column and sediments of the Cariaco Trench show that CH4 is non-conservative in both environments. Concentration differences between the sediments and adjacent overlying water suggest that the sediments are the source of the water column CH4. Co-metabolism of CH4 by sulfate reducers appears to be the CH4 sink in anoxic environments. |
